Pb + Mg(NO₃)₂ → Pb(NO₃)₂ + Mg
This reaction would NOT occur because Pb is less reactive than Mg and as such Pb cannot displace the Mg in order for the reaction to occur under normal conditions.
Mg + Fe(NO₃)₂ → Fe + Mg(NO₃)₂
This reaction would occur. This is because Mg is more reactive than Fe and as such can displace it in the reaction, thus allowing the reaction to occur under normal conditions.
Cu + Mg(NO₃)₂ → Cu(NO₃)₂ + Mg
This reaction would NOT occur. Mg is more reactive than Cu, and as such copper cannot displace magnesium in order for the reaction to occur under normal conditions.
Answer:
About 25 kPa
Explanation:
Pressure decreases with height above sea level.
The calculation is rather complicated, so I will refer to the figure below.
It shows that the pressure at 10 km is about 25 kPa.
Answer:
The glass of water weigh once the antacid pill has dissolved will be less than the 179 grams due to evolution of carbon dioxide.
Explanation:
Mass of effervescent antacid pill = 4.00 g
Mass of water = 85 g
Mass of glass = 90 g
Total mass of the substances together : 4.00 g + 85 g + 90 g = 179 g
Effervescent antacid pill , moment it get dissolved in water carbon dioxide gas is evolves and escape from the solutions.
This means that mass of the weight of the glass of water with antacid dissolved in it will be less than 179 grams.
Answer:
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. ... The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
